Icon is delighted to welcome Accredited paintings conservator and Constable expert Sarah Cove ACR to deliver Icon’s 2026 Annual Lecture.
2026 marks the 250th anniversary of John Constable’s birth. With landmark exhibitions exploring the artist’s life and work at the Tate, British Museum, Gainsborough’s House, Ipswich Museum and more, the celebrated painter’s landscapes of rural England continue to reach audiences everywhere, reflecting the everyday beauty of the natural world.
There seems no better time to highlight the groundbreaking work of paintings conservator Sarah Cove ACR and the Constable Research Project. Using technical examination and scientific analysis, contemporary literary sources, artists’ manuals and the artist’s voluminous correspondence, Sarah has established a ’technical chronology’ that details Constable’s artistic development, his use of innovative materials and methods and his profound, and possibly unexpected, influence on later landscape painters. This work has aided scholars with art historical questions, and also acts as a tool for attributional purposes. Sarah has been instrumental in the discovery of many ‘lost’ Constables, but the incredible recent discovery of the full-size sketch for ’The Cornfield’ is a fitting triumph to mark the 40th anniversary of her research.
Hanging in obscurity for 50 years at the Jefferson Historical Society and Museum in rural Texas, the sketch had been long misidentified as a copy. Sarah’s discovery cemented the work as the largest-known preparatory study for ‘The Cornfield’, with the piece selling at auction for $225,000 via Heritage Auctions in June 2026.
This will be Icon’s eighth annual lecture, with previous speakers including international conservation thought leader Professor Jane Henderson, award winning journalist and broadcaster Samira Ahmed, Dr Nick Merriman, then chief executive of the Horniman Museum and Gardens, Sarah Scaturro, the Eric and Jane Nord chief conservator at the Cleveland Museum of Art, and the president of ICOMOS-UK Clara Arokiasamy.
Icon’s chief executive Emma Jhita said:
Sarah’s remarkable work on the Constable Research Project shows how rigorous technical investigation can transform our understanding of cultural heritage - a powerful reminder of the value of conservation research and the extraordinary insights it can bring.
As we mark Constable’s 250th anniversary, I am delighted that Sarah Cove ACR will deliver Icon’s 2026 Annual Lecture, sharing the expertise, perseverance and innovation behind the landmark rediscovery of the full-size sketch for The Cornfield.
Icon's 2026 Annual Lecture will take place online on Wednesday 7 October, 6:30pm to 8pm.Tickets are free for Icon members and just £10 for non-members. Find out more and book your tickets here.
